T0 a?? trimm it may confier/1.'

'e it known that we. Pirrm: T. CorrncLn and JoinY Ihn-mun. citizens ot the United States, residing at Da vton and Cincinnati. in the counties ot' Montgomery and Hamilton, respectively` andiqtale ot Ohio, have invented certain new and useful Improvements in Driving liliechanism: and we do declare the following to be a full` clear. and exact description ot' the invention. such as will enable others skilled in the art to which it appertaina to malte and use the same. reference being had to the accompanying drawings. and to the letters and figures' of reference marked thereon. which form a part ot this specification.

This invention relates to certain new and useful improvements in driving mechanism for washing machinea.

The object of the invention is to provide Such mechanism whereinY the operationS ot` washing and wringing the clothes niav take pla e simultaueousl'v. To the above end. the clothes may be wrang from the tub in which they are washed directly` or the wringer may operate on previouslv washed clothes while other clothes' are being washed. the wringer being adiustable or movable to various positions relative to the tub.

Referring to the accompanying drawings., Figure l is an elevation of a laundry instaliation constructed and arranged accord ing to our invention. Fig. 9. is a bottom plan view of the same: Fig. is a top plan view ot' the saine: Fig. `lis a detail view ot a portion of the wringer gearing; Fig. is a section on the line a e of Fig. `i. showing the wringerswivel and gearing: Fig. G ia a detail plan view of the locking plate instrumental in holding the wringer in its various positions; and Fig. 7 is a view of the slotted plate instrumental in controlling the gearing between the motor and the wash tub.

'lliroughout the Specification and drawings, similar reference characters indicate corresponding parts.

Referring more particularly to the draw ings, l represents a wash tub of any preferred type which is supported on legs Q. Within said tub, and at the bottom thereof. is a dolly wheel or agitator 3 mounted on a vertical Shaft 4 extending down through the bottom ot' said tub and through a stufing box Specification of Letters Patent.

Serial No. 624,181.

.1. The said dolly wheel 3 is provided with pins G which extend upwardly in the tub and engage the clothes within said tub to agitato the same during the oscillation of the dolly wheel. The said dolly wheel is oscilla ad by means of a pinion 7 mounted on the ower end ot' the sha'tt l and engaged hv a resiproeating powendri ven rack S. Attached t0 the rack S is one end ot' a spring 9, the other end ot' which is attached at 10 to the tub 1 or other convenient point, Fig. Q. The Said spring acts to disengage the rack S and pinion T. The member 11. pivoted at 12, is held against the raclc S by a reciprocating rod 14. The inner end oi the rod 1l engages the member 11` while the outer end is mounted in a slotted plate 15. The said outer end of the rod 14 iS provided with a finger piece 16 by which it is manipulated` and a collar 17 which lies on the inner side of Said plate 15. lVhen said rod is reeiprocated in the slot in plate 15, the inner end will reciprocate the member 11.` therebv permitting the pinion and rack to engage when the rod is in one position. and to disengage under the influence of the Spring il when said rod is in the other position. A frame 13 is provided which serves as a support for the pivot 1Q of the member 11. a bearing 'for the dolly wheel shaft 4, and a guide for the rod 14. The rack 8 is attached to one end of a connecting rod 18, the other end of which is pivfted to a crank pin 19 on a worm gear '20. The said gear Q0 is mounted on a vertical `shaft Q1 (driven from the mrtorl and is in engagement with a worm 2Q on a horizontal shaft :23 journaled in hearings Q4 attached to the bottom of the tub. The shaft 23 is provided with a` pulley Q5 connected with a motor 2G. preferably of the electric type, bv a belt Q7. The Said motor Q6 recipro Cates the rack S, and the extreme high Speed of Said motor is reduced to a comparatively low speed by the worm gearing 2Q and Q1. Then the rack 8 is placed in engagement with the pinion 7. bythe rod 1l, the dolly wheel 3 will be cscillated by the rack 8.

Having described the particular driving connections between the motor and the dolly wheel ol the tuh. we will next describe the construction ot' the wringer.

The vertical shaft 2l is journaled in an upright elongated bearing; E27 supported on the side of the tub by brackets 28. The upper end of the bearing 27 terminates in a locking flange or plate .29 and a tubulaistem 30. Pivotally mounted on said stem 30 is a sleeve 31 to which is attached a wringer board 32. The sleeve 31 is provided with a flange or plate 33 which coincides with the plate 29, and together they form a turntable. The said sleeve 3l is also provided with a projection 34 which receives a spring-controlled pin 35. The lower end of the pin 35 passes through an aperture in the plate 33 and is adapted to enter any one of a series of apertures 36 in the plate 29. The wringer board 32 and therewith the wringer, may thus be swung around the stem 30 to various positions in which they may be locked by the pin 35 and openounted on the swinging supporting board 32 is the wringer 37 of any well known type. and which is provided with upper and lower rollers 38 moving in unison through the medium of gears 39. The shaft 40 of the lower roller is provided with a clutch member 41 splined thereto and adapted to be placed in engagement with a similar clutch member 42, see F ig. 4. The clutch member 42 is mounted on a short shaft 43 journaled in a bearing 44 extending from the wringer board 32. The clutch member 41 is provided with a groove 45 which receives a pin 46 on a lever 47 pivoted at 48 to the wringer board. Nhen the lever 47 is oscillated, the clutch member 41 will be thrown into and out of engagement with the clutch member 42, and thus the operation of the wringer controlled. Mounted on the short shaftr43 is a bevel lgear 49 in mesh with a similar gear 50 on the upper end of the shaft 21. The shaft 21 is driven from the motor 26 through the belt 27, shaft 23 and gears 20 and 22, as before described.

The rollers 38 of the wringer are driven from the shaft 21 through the miter gears 49 and 50, and clutch members 41 and 42 when said clutch members are placed in enagement with each other by the lever 47. he wringer as before stated, may be swung around upon the stem 30 to various positions to wring the clothes from one tub into another, and said wringer may be locked in its position by the pin 35 before referred to. From the foregoing description it will be seen that the washing machine and wringer may be operated from the same source of power and each operated independently or simultaneously as desired, thus enabling the washing to be done in the washer while the wringer is wringing through the rinse waters the clothes that have previously passed through the washer.
